I think so, I pretty much pasted from Beowulf (cudos to Colin!)
/* Setup the data structures needed for the EGTB access code */
void InitialiseTB(void) {
fprintf(stdout,"Checking for Tablebase Files\n");
LargestTB = IInitializeTb(TB_PATH);
if(LargestTB != 0) {
void *TBCache = malloc(CACHE_SIZE);
if (TBCache == NULL) {
fprintf(stdout,"Not Enough memory for EGTBs!\n");
LargestTB=0;
return;
}
fprintf(stdout,"Including %d-man Endgame Table Bases\n", LargestTB);
FTbSetCacheSize(TBCache, CACHE_SIZE);
}
}
I used 2 MB cache, but there might be a problem because the task manager didn't
indicate any allocation of 2 extra megabytes.
"LargestTB" is the correctly spotted as 4 (since I don't have 5 man at the
moment), so something is working.
